Description
Technical field
It is the present invention relates to a kind of processing tool, in particular to a kind of for processing the processing work of high-speed EMUs car body skirtboard
Dress, belongs to high-speed EMUs car body processing tool technical field.
Background technique
Most of key equipment of high-speed EMUs is lifted under vehicle, EMU on the line high-speed cruising when can generate very
Strong air pressure wave, therefore the fortuitous event that sandstone, ice cube or other objects divide into the raw high speed strike of preparation with vehicle is sent out often
It is raw, seriously jeopardize the application safety of bullet train.To reduce air drag, equipment under protection and tool car, it is ensured that high speed motor car
Under the vehicle of the high-speed EMUs of the safe operation of group, 200 km of speed per hour and the above speed class, it is necessary to which design and installation, which have, to be led
Stream protects, equipment compartment under the totally-enclosed vehicle of maintenance function, and equipment is mounted in equipment compartment under vehicle；Equipment compartment is mainly by skeleton, bottom
The skirtboard of plate, the end plate at both ends and two sides surrounds, generally box-shaped full-closed structure, is carried using frame-type skeleton.According to it
The difference of function, equipment compartment apron board are divided into air draft, air inlet, sliding window, hermetically sealed 4 class again.Air draft skirtboard is equipped with discharge window, air inlet
Skirtboard is equipped with strainer and labyrinth structure, and sliding window skirtboard is mainly used for water tank and adds water.Skirtboard is distributed in equipment compartment two sides, bottom in arcuation
Portion is connected to skeleton side bar through arc hook, and upper end is fixed by bolts in car body side bar, in order to install and overhaul.Therefore skirt
Plate is the critical component of equipment compartment under motor train unit, covers vehicle using the skirtboard to match with vehicle body transverse shape and divides into
It is standby, lateral protection is provided for hanging device under vehicle, both can reduce air drag, is hit prevented also from high-speed cruising bring sandstone
It calls a taxi lower equipment, can be protected using equipment of the skirtboard to the car bottom under high-speed travel state, the installation of skirtboard
Cheng Shi first processes connecting hole on skirtboard, and then skirtboard is fixed in the pre-drilled hole of car body.
Existing high speed motor car equipment compartment aluminum alloy apron board is made rear welding of 7.4 meters of profile groups of machining again,
Since skirtboard profile size is larger, relatively thin, poor rigidity is complex-shaped and irregular, is also easy to produce in clamping process and process
Deformation, proposes higher requirement to process equipment, processing technology, tooling, and processing characteristic is, and 1, large-scale processing is needed to set
It is standby, gantry machining center is generally used in the prior art；2, it since the shape of skirtboard is not a plate, can not directly be set in processing
It is processed on standby workbench, therefore, fixed skirt need to be carried out by tooling.
The common positioning clamping mode used in the prior art, processing efficiency is lower, and clamping leads to positioning accuracy repeatedly
Not high, working hour consuming is more, and the effect that profile deformation is controlled in process is not very good, and skirtboard deformation after processing is caused to surpass
Difference, it is difficult to guarantee that the dimensional accuracy of skirtboard after machining, processing quality are greatly affected.In addition, the processing of the prior art
Its modulability of tooling is poor, it is also difficult to which the clamping for adapting to a variety of skirtboards uses, and is unable to satisfy secondary process different type skirtboard
It is required that there being the small limitation of the scope of application.High-speed EMUs vehicle vehicle is numerous at present, and streamlined appearance design is in diversification
Trend, car body is streamlined to be mainly reflected on side wall, and side wall of aluminum alloy bodywork is highest big as high-speed EMUs appearance requirement
Component often carries out personalized, differential design in design, and skirtboard needs match with car body transverse shape, therefore lead
Causing skirtboard, often product category is various in high-speed EMUs vehicle, and disparity items differs greatly, during processing just
It is big there is tooling difference, the characteristics of poor universality.
The general processing work for the high-speed EMUs car body skirtboard processing that can eliminate drawbacks described above is provided for this reason, it may be necessary to develop
Dress.
